One of the causes of asthma is dust. Dust and dust mites are inevitable in your home, but that doesn’t make life any easier on people with asthma who are sensitive to them. The CDC recommends avoiding down-filled bedding and pillows and putting covers on your mattresses and pillows to create a barrier between you and those dust mites. You could also install air filters in your home and use a vacuum cleaner equipped with a HEPA filter and professional floor cleaning!
